ARNET T. JOLMA, OF CLATSKANIE, OREGON.

STEAM-WHISTLE.

Specification of Letters Patent.

Application filed December 19, 1910.

Serial No. 597,984.

To all whom it may concern:

Be it known that l, Anxn'r T. Jomn, a citizen of the'llnited States.residing at (latskanie in the county of Columbia and State of Oregon,have invented a new and useful Improvement in Steam-' lnstles. of whichthe following is a specification, reference being bad to theaccompanying drawmgs.

My invention relates to a class of devices appertaining to engines andboilers, more particularly those used in logging camps and especiallyportable engines and boilers.

The object of my invention is to provide a device whereby a whistle maybe ettecte ally sounded and signals thereby given from a point distantfrom the whistle. I attain these objects as well as other advantages. bythe construction combination and arrangenu-nt of parts illustrated inthel acunnpanying drawings which form a part hereof.

Figure l is a side elevation of a whistle partly in section with steampipe connection Fig. 2 is a plan view showing the visible portionsof mydevice.

Like numerals and letters refer to like parts in both views.

A is a vertical pipe leading from a suitable connection with a steamboiler.

13 is a whistle barrel secured on a rod X.

l is a whistle cup secured on the rod X below the barrel l3 and alsoupon the upper end of the pipe A. Within the cup C is formed a valvewall 3 with valve opening 4 therein. A horizontal valve stem 5 extendsfrom without the cup C into its lower portion through the opening 4and-has on its inner part a valve cap ti. The valve stem 5 is alsoprovided with a coil spring 7 on its inner end which engages the innersurface of the opposite all of the cup C. A horizontal frame I) isfixedly secured to the pipe A by means of the bolts 8, 8'. A rightangled lever 9 is pivoted by its vertical arm on the bolt 8. Near theupper end of v the lever i an arm 10 is rigidly secured and has awhistle lever 10 pivoted therein. There is also a whistle cord 10secured to the upper end of the lever 10. The lever '10 is provided withan integral valve opcrating pin 11 in position to engage the end of the'alvc stem 5. spring]? p ovided for the lever 10'. A horizontal rod 13extends through the lower engaging the side of the frame There is also arecoil.

the frame D a recoil spring 16 is placed around the rod 13, one end ofthe spring- D. The inner end of the rod 13 is threaded andhas thereonadjusting nuts 17 which retain the The outer part of the spring 16outwardly. rod 13 is also threaded and has thereon adjusting nuts 18which engage the side of the frame I). is a fork 19 carrying a rotatablymounted drum 19 therein. The drum 19' is provided with a handle 20 andon one end also has a ratchet 21. A nawl 22 is pivoted on a pivot in thefork 19 in position to engage the ratchet 21. A cable 24 is secured tothe drum and extends about it in reverse direction to that of theratchet teeth and away from the drum a suitable distance;

Itwill now be seen that when an engine and boiler carrying my device isplacedinposition for operation, for example in a timbered country, thecable 24: is drawn away to a point from'which it is desired to transmitsignals. The slack of the cable is takenup as desired by turning thedrum 19'. Inthe same manner the cable may be lengthened 0r shortened andthe whistle sounded from any distance. Upon pulling the cable the lever9 moves to its dotted position and the other parts likewise, as showninFig. 1. This causes the pin 11 of the lever 10 moving as a unit with thearm 10 to engage the valve stem. 5 and sound the Whistle. It will alsobe seen that if the engineer desires to sound the whistle while near it:he may do so by pulling upon the cord 10 which moves the lever 10 andcauses the pin 11 to engage the valve stem 5 thus sounding the whistleWithout any inoven'ient of the remaining parts of my device.

My whistle is intended for use upon any boiler employed in work whichrequires signaling from a distance and is particularly useful on boilersfor donkey engines used in hauling logs and timbers through rough landsbymeans of cables and where the crew must. work at considerable distancefrom the engine and engineer. fore used to sound the whistle on suchboilers have proved unsatisfactory and either t'ail entirely to soundthe whistle or else cause it to remain in a position to sound con-Patented Au fs, 1911.

()n the outer end of the rod 13,

The devices heretoti nuously. I contend that I have overcome theditiieulties in this respect previously encountered and that my devicewill effectively sound the Whistle for the intended signals and does notpermit it to sound continuously.

Having thus particularly described my invention I claim:

A steam-Whistle of the kind described, provided with a whistle pipe anda Whistle having a valve stem extending without the same Whistleoperating means comprising a horizontal frame D secured to the Whistlepipe, 21 rightangled lever 9 having its verslidable horizontal rod'13mounted in bearings within the frame D, the inner end of the rod 13being pivoted in the lower end of thelever 9, the outer end beingforked, a drum rotatably mounted in said fork, a ratchet upon the drum apawl pivoted on the fork in position to engage the ratchet, a cablesecured to the drum and extending about it in a direction opposite thatof the 'atchet teeth, also means upon the rod to retain the lower arm ofthe lever 9 in vertical position, substantially as described.
